SEO in 2026 is two jobs, not one. Classic search (Google, Bing) still rewards clean meta tags, structured data, and correct hreflang. But generative engines (ChatGPT, Claude, Perplexity, Google AI Overviews) are a new surface — and they read your site through llms.txt and decide whether to crawl you via AI-specific robots rules. This collection assembles 6 free, browser-based tools that cover both halves. No signup, no backend, copy-paste ready.
TL;DR — The AI-SEO Stack at a Glance #
| # | Tool | Layer | Role | Open it |
|---|---|---|---|---|
| 1 | llms.txt Generator | GEO | The “robots.txt for AI” — tell ChatGPT/Claude/Perplexity crawlers how to read your site | Open tool |
| 2 | robots.txt Generator | GEO + Classic | Standard crawl rules + AI-crawler controls (GPTBot, ClaudeBot, PerplexityBot, CCBot, Google-Extended) | Open tool |
| 3 | Meta Tags Generator | Classic | SEO title/description + Open Graph + Twitter Card in one paste | Open tool |
| 4 | Schema.org JSON-LD Generator | Classic + AI | Structured data (Article/Org/FAQ/Product) — rich snippets that Google, Bing, AND AI search all consume | Open tool |
| 5 | Hreflang Generator | Classic | Multi-language / international SEO — the alternate tags every global site needs | Open tool |
| 6 | OG Card Preview | Classic | Preview your Facebook / Twitter / LinkedIn share card before you ship | Open tool |
The Assembly Order #
Start with the GEO layer (1 + 2) — this is what most sites haven’t done yet, and it’s where dibi8’s edge is. Generate an llms.txt so AI crawlers understand your structure, and a robots.txt that explicitly allows (or blocks) GPTBot/ClaudeBot/PerplexityBot. In 2026, being citable by AI search is the new “ranking on page 1.”
Then the classic on-page layer (3 + 4 + 5) — meta tags for the snippet, Schema.org JSON-LD for rich results (and AI engines increasingly parse JSON-LD for facts), hreflang if you’re multi-language. These are table stakes that still move rankings.
Finish with the share layer (6) — preview your OG card so links look right when shared. Social signals + click-through both matter.
Why “GEO” Is the Differentiator #
Classic SEO tools are a red ocean — a thousand meta-tag generators exist. The GEO half (llms.txt + AI-crawler robots) is the 2026 blue ocean: a brand-new standard, few tools, and it’s exactly where AI-era discoverability is decided. This stack is the only place that bundles both halves with the AI-crawler angle front and center — because dibi8 is an AI tools site that practices its own GEO.
Host the Site These Tags Live On #
These tools generate the code; you still need a site to put it on. A reliable host with clean crawlability matters for SEO: HTStack (HK VPS, the IDC behind dibi8.com) or DigitalOcean ($200 free credit). Want the deeper playbook on AI-era discoverability? Our $19 Gumroad bundle includes GEO and content-optimization skills.
Verdict #
SEO in 2026 = classic on-page plus generative-engine optimization. Most sites do the first half and ignore the second — which is exactly the gap to exploit. Run all 6 tools in order: lock down how AI crawlers see you (llms.txt + robots), nail the on-page basics (meta + schema + hreflang), polish the share card. Free, browser-based, ten minutes. Then go get cited by the AI engines your competitors forgot to optimize for.
